Application fi1ed September 17, 1906. Serial 11o. 334,916..

Be it known-that I, JACOB 'FnLBnL, a citi j zen of the United States,and resident of the lll borough of Manhattan, city of New York; in'thecounty of New York and State of New York, have invented certain new anduseful Improvements in Type writing Machines, of which the following isa specification.

My invention relates more especially to the ribbon mechanisms oftypewriting machines and has for its main object. to pro-' vide animproved construction wherein aribbon normally removed from the printingpoint and having a plurality of fields of different characteristics may,under the in fluence of the printing keys, be moved to cover theprinting point with any desired -hereinafter more fully describedan'd'p'ar ticularly pointed out in the claims.

- The invention is shown as applied to a Monarch typewriter but thenature .of 'the invention is such that it maybe readily I adapted toother forms of writing machines.

is an enlarged vertical sectional view of' some of the parts shown inFig. 9. Fig. 11

is. a detail side View of the upper part of the mechanism shownzin Fig.8. Fig. 12 is- I an enlarged front elevation-of a ribbon vibrator. andassociated parts and showing .a further modification, of my; invention,certain parts being broken away. Fig. 13 is a vertical sectional viewtaken centrally of the vibrator shown in. Fig. 12.. Figs. 14', 15

and 16 are, enlarged side elevations partly in section of still anothermodified construc machineis shown as comprising a base 1,-

corner, posts 2jand a top plate 3. Key levers- 4 are fulcrumedon a.fulcrum plate -5,' each key lever being, provided with arestoringspring-,6 and having pivoted to it at 7 a sub-lever 8. The lower endportion'ofeach sub-lever is slotted to cooperate with a fixed abutment 9and the upper end of the sub-f lever is connectedby .a link, 10 to atype bar 11, said type bar being pivoted in a hanger 12 secured to asegmental hanger support 13' on which the hangers 12 are arranged insegmental series. The. type bars cooperate with. the front face of aplaten 14 which is diagrammatically illustrated in Figs. 1 and 2, saidplaten being supported in .a carriage (not shown) and the carriage beingcon nect-ed by a band or strap 15 with a springv drum 16 whichconstantly tends to draw the carriage and platen 14 leftward across thetopplate. The leftward movements of the platen and carriage arecontrolled by letter space feeding mechanism which is of the usualconstruction but is omitted from the drawings, -said mechanismcomprising devices which are connected by a link 17 with the centralrearwardly projecti arm 18 of a .universal bar frame, which ramecomprises in addition to the arm 18, .side arms 18*, a rock shaft 19mounted to turn'on screw pivots 18 threaded into openings in the base ofthe machine, and a universal bar proper 20, the latter extending fromside to' A ribbon 21 is wound upon a pair of ribbon spools 22 onedisposed at each side of the machine forwardly of the platen and abovethe top plate. As herein shown the ribbon 21 is divided intolongitudinal stripes or fields a and b of different characteristics,

that is to say, the field a may be of one color, such as black, and thefield b of another and different color such as red, for example; or thefield a may berecord ribbon and the field 6 copying ribbon. The ribbonmay be fed longitudinally from one spool to the other and vice versa byany suitable ribbon feeding mechanism, that shown in the drawings beingthe usual mechanism of the Monarch machine and comprising foreach'ribbon spool a beveled gear 23 operatively connected with itsassociate spool and meshing with a beveled pinion ,24 at the forward endof a horizontal shaft 25, said shaft carrying at its rear end a beveledpinion 26. Each pinion 26 is adapted to mesh with a driving pinion 27fixed to a horizontal driving shaft 28 journaled in lugs 29 dependingfromthe under side of the top plate and extending from side to side ofthe machine. The driving shaft is connected with and receives motionfrom the spring drum 16, the connections consisting'of beveled gears 30and 31, the gear 30 being operatively connected with the spring drum andthe gear 31 with the driving shaft 28 by a pin 31 and slot 31 in such away that while said gear31 and said shaft turn together yet said shaftmay be moved endwise relatively to said gear while the latter is heldagainst movement lengthwise of the shaft by the gear 36 and one of thebrackets 27. The endwise movement of the shaft serves to connect one oranother of the driving pinions 27 with its associate pinion 26 and tocause one oranother of the ribbon spools 22 to be turned to wind theribbon thereon.

Midway between the ribbon spools the ribbon 21 is threaded through avibratory ribbon carrier or vibrator 32 which may be of the usualconstruction and which is guided and supported in the upright arms 33 ofa bracket 34 secured by screws to the top plate. The stem 36 of theribbon carrier carries a cross pin 3Twhich cooperates with the slottedforward end of an operating lever 38, thereby pivotally connecting saidoperating lever with said ribbon carrier. The operating lever isfulcrumed at 39 on a fixed pivot in an arm or bracket 40 depending fromthe under side of the top plate and is connected in a manner now to beparticularly described with the arm 18 of the universal bar frame In theform of my invention shown in Figs. 1 to 7, inclusive the rear arm ofthe operating lever is pivotally connected at 41 with a link 42; Thelower end portion of the link 42 is threaded and screwed into a threadedstem or socket 43 of a stirrup-like strap or apertured member 44, saidmember in addition to the stem comprising a body portion 45 formed withan opening 46, the

stem or socket being above the body portion as shown in Fig. 2. By meansof the threaded connection between the lower end of the link 42 and thestem 43 the member 44 ma be suitably adjusted when the machine assembledand after adjustment may be maintained in proper relation with the link42 by a locking or check nut 47. As best shown in Figs. 3 and 4, theopening or apcrture 46 is circular at its upper part and squared at itslower part. Said opening may be formed by cutting a circular opening inthe body portion 45 and thereafter cutting out or squaring the lowerportion of said opening so that while the upper half of the opening isrounded and the lower half square or angular the lateral dian'leters ofthe two halves are equal. The strap 44 is connected with the arm 18 ofthe universal bar frame, by a connecting member or device, best shown asa whole in Fig. This device comprises a portion 49 which is received inthe opening at of the stirrup or strap; a larger disk-like portion '50at one side of the part. 49 and serving to retain the strap 44 in placeon the part 49; and oppositely projecting hub portions 51 and 52concentric with the disk 00. The connecting member is rotatively mountedon the arm-1S by the hub 52, which is received in a circular bearingopening 53, formed in said arm and there retained by a headed screw 54,threaded into the end of the lmb. The head of the screw abuts one sideof the arm 18 and the portion 49 abuts the other side of said arm, theconstruction being such that endwise motion of the connecting membertransversely of the. arm 1.8 is prevented, but said member may be turnedor rotated to vary the position of the part 49 within the strap 4-4. Inthe present instance, as shown best. in Figs. 3 and 4, the portion 49 iscircular in cross section to a large extent but is slabbed oil or cut.away on one side, as indicated at 55, so that the rounded face of saidportion 49 is at a greater distance from the center of motion than isthe cut-away 55. The radius of the rounded face of the portion 49 issubstantially equal to the radius of the circular partof the opening 46in which it is adapted to turn so that when the part 49 and its openingare in the relation shown in l ig. i, the upper portion of the part. 4!)tits closely in the upper portion of the opening while at the lowerportion thereof there is a considerable space between the bottom tlatwall of the opening and the cutawayflat faceoo. this space beingindicated in Fig. 3 by the numeral 56, and affording an independentrelative movement between the part 49 and the stirrup. The outer orright hand fare of the disk-like part is provided with two holes ordepressions 57 and 58 diametrically opposite each other. Cooperativewith the lO-ti lllt depressions 57. and '58 is a lug or head I carriedat the free'endjofaspring arm .69

which is secured toj thearm '18 of the uni-.

' versal bar framejby. a headed-screw 611 and a pin 62, as best 'showninFig. 5.} v he lug 59 and spring arm 60 comprise a Y i detent which isprevented from turmngas a whole on the arm-18. The-construction 1s suchthat when the connectingv member is ro- "tated the free end o-fthde'tent is forced out of one of the holes 57, 58 of the diskand therounded .lug or headj 59 engages' with the other of said holes tomaintain the connect ing member in the position tofvsghich it has beenadjusted. The connecting men berlmay be given rotary movementindependently of the operationof the machine by any suitable means. Asshown in Fig. 2.1a v

driven crosswise through the hub-portion'5l,"

pin 63 is the end portions. of; said" p'in cooperating with enlargedopenings in a cup-like member 64, said member being secured'by a pin.'65 .to the innerv end ofa finger rod 66. .The finger rod extendslaterally outward through an enlarged opening 67 in the right-hand;

- side of the base 1, and outside of the base 1 said finger rod. isprovided with a fingerbutton 68, by turning which the connecting membermay be turned in its bearing in the arm 18'. The up and down movementsof.

said arm 18 under the-influence ofitheprint- -.ing key levers will notbe interfered with .by

the finger rod 66, because the opening 67 is of sufiicientsize to letthe finger rod reciprocate up and down to the necessary extent while,the openings in the cup-like member 64 are'large enough to prevent. anybinding action on the ends of the pin 68.

Referring to the operation-of the 'parts thus far described, when theopening 57 in a the (llSk is in cotiperation with thespring detent'. theportion 49 integral with said disk will normally .be in the relationwith the stirrup 44 shown in Figs. 1 and 3. It-will be apparent from aconsideration of these figures that when any key lever is operated v theuniversal bar and the arm .18 will move downward some distance beforepicking up the link 42, this distance being represented by the space 56.K In other words, during the initial stage of the downward movement ofthe universal bar frame the ribbon vibratorand its operating lever andactuating link will remain qu escent 1n normal position.

As soon as the universal bar frame has moved downwardly far enough tobring-the cut-away or fiat face 55 into contact with the bottom of theopening 56 the link 42 will begin to 'move downwardly and-the ribbonvibrator, will be raised. The parts are, so proportioned andarrangedthat on the completion of the downward movement of the universalbar frame the vibrator will' have been lifted far enou 'h to bring the-uper or black field a of tli e ribbon opposite the printing point inposition to coiiperate with the actuated ,type bar. It will be apparentthattas long as the connecting member and, [universal bar-framearemaintained in the relation shown in Figs. 1., 2, 3 and 5, the ribbonwill be raised at each printing operation-to. the same height and thatthe type impressions will follow in a path longitudinally, of the ribbonand along the upper portion or black field a thereof. If desired,

-there may be employed a returning-spring 3'8 and astop38 for thevibrator lever 38, as shown .at Fig. .1. This spring is conelected atone end to the lever and at the other end to the-top plate. The stopdepend's from' the top plate. WVhen it may be desired to use the lowerportion or red field b'of the ,ribbon the finger. button 68 may be 1turned adist-ance of 180 or until the connecting. member hasbeen-turnedto a sufficient extent to disengage'the spring from the hole 57 andengage it withthe hole58. This new-position of the jparts'is illustratedin Fig. 4.. From a consideration of this figureit will be seen that thecut-away 55 is nowv at the upper part of the opening 46 and that therounded faceof the part '49 is in vcontactive engagement with the bottomof said opening 46, the construction being such that the fit' betweenthe part 49 and the bottom cross bar of the strap is'a' comparatlvelyclose one and lostmotionis' done away with. Consequently as 'soo as theuniversal bar frame begins to move downwardly under theinfluence of aprlntmg key lever, the link 42 will-begin to move downwardly andthevibrator 32- will begin to move upwardly.

The parts are so proportioned and arranged -that on the completion ofthe downward movement'of the universal bar frame the ribbon will havevbeen oved upwardly a greater extent than when the arts were arranged aspreviously describe and the lower field b will be presented at 'theprinting point. As long as the part 49' is maintained by the springdetent at the position illustrated inFig. 4 the ribbon will. be movedupward to substantially the-same extent dur- I my present invention; and,in Figs. 8 to 16.

inclusive, of the drawings I have illustrated examplesof some of suchchanges. In Figs. 8 to 11,- inclusive, the eccentric connection insteadof being at the universal bar end of the link 42, as in the firstinstance, is at the upper end of said link and is carried by theoperating lever 38. The lower end portion &

of the link 42 is pivotally connected at'69,

- with the arm 18 of the universal bar frame ing lever 38 is providedwith a bearing opening- 70 which cooperates with the hub 52 of themember '48, as shown in Fig. 10, said,

member 48 being held from endwise motion and being adapted to turn orrotate in the manner previously described. The member 48 is adapted tobe maintained in either of its operative positions on the lever 38by aspring detent 71 which cooperates with the i holes or o enin s 57 and 58in the disk 50 P s a the lug 40 being cut away slightly as shown at 72in Fig. 8 to permit the detent 71 to be secured in place on the lever 38by a screw 73. In the present instance the right-hand hub portion of themember 48, instead of being cylindrical in the first instance, issquared as indicated at 51, the squared shape .enabling it to properlycooperate with a manually controlled adjusting key. The head 74 of saidkey is provided with a squared opening or depression 75 which is adaptedto fit over the hub 51 but is normally disengaged therefrom. The head 74is suitably secured at the inner end of a rod or shaft 75 mounted inlugs 7 6 depending from the top plate and extending laterally outwardbeyond the right-hand edge thereof. The outer end of the rod 75 isprovided with a finger button 77 and a spring 78 coiled around said rodand compressed between a collar 79- thereon, and one of the lugs 76 actsto maintain said rod normally in the position shown in Figs; 9 and 10wherein it will be noted the head 74 is entirely disengaged from the hub51 and a movement of the vibrator and its actuating connections may beeffected independently of the manually con-. trolled adjusting key.

With the parts in the position illustrated in Fig. 8 the mechanism willoperate to bring the upper field a of the ribbon to printing positionwhen the various printing keys are operated. When it is desired to rintfrom the red field b of the ribbon the ger button 77 .may be pressedinward,

' overcoming the force of the spring 78 and causing the head 74 toengage with the hub 51*. Thereafter the finger button 77 may be turnedto rotate the eccentric or connecting member through a distance of 180or half a.

. turn and'so as to disengage the detent from .with the hole 58.

the hole 57 and bring it into engagement Then the fin er button 77 maybereleased, permitting tie spring 78 to disengage the head 74 from the hub51". With the eccentric member thus readjusted the ribbon will be liftedfar enough to present the red field b to the types at each printingoperation, as previously explained. Certain of the features of theconstruction just described are reserved for another application.

It will be seen that by my present invention I provide means operativeto effect a variation in the throw of the ribbon carrier or vibratorwithout changing the place or point of connection between the means formoving the vibrator and the means for actuating said first named means;that said throw-varying means comprises a pivotal connection oreccentric device adjustable to vary the extent of movement of theoperating lever without, however, altering the length of the power armof said lever; and that the said throw-varying means is adjustableindependently of the operation of the machine. r

A further modification is illustrated in Figs. 12 and 13 wherein theconnecting member or eccentric device is shown as connecting thevibrator 82 and the vibrator operating lever 38. In this constructionthe usual stem of the vibrator is replaced by a strap or stirrupcomprising side arms 79 depending from the sides of the vibrator andjoined at their lower ends by a curved part 80. In this instance thecross head 32 of the vibrator forms the top of the strap. A connectingmember or eccentric device 81 is arranged within the strap and is proyided at its front side with a flange 82. A thin plate 83 shaped like theeccentric device proper is suitably secured at, the rear of saideccentric device and cooperates with the flange 82 to form a peripheralgroove in the. eccentric device,

which groove fits over the inner edges of the strap, as will beunderstood from-Fi g. 13. A bearing opening is formed in the eccentricdevice 81 and plate 83, which opening receives a bearing stud S4projecting forwardly from and integral with a bracket 85 secured by apin 86 to the front 'end portion of the lever 38. During the vibratorymovements of the lever 38 it carries the eccentric device 81 hp and downwith it. Said dcviceis also rotative on the stud 84, a forwardlyprojecting finger piece 87 being provided for ready manipulation. Aspring detent- 88 is pivoted on a screw 89 on the vibrator lever 38 andcooperates at its free end with depressions or openings 90 and 91 in theeccentric device to maintain the lat ter in its working positions. Whenthe detent S8 and the opening 90'are in cooperation, the eccentricdevice is normally positioned as shown in Figs. 12 and 13, with thecutaway or straight face 81 at the top. With 1 the eccentric device sopositioned or set, it is obvious that when the lever 38 is actuated byany printing key, said lever will move upwardly some distance beforepicking up the vibrator, this distance being represented I 34 andcobperating with a notch by the numeral 99. The parts are proportionedso that this limited movement of the vibrator is sufficieut to bring theupper field a of the ribbon to. the printing point.

, On the return movement of the lever 38 the rounded lower part of theeccentric engages the curved part-80 of the strap and restores thevibrator to normal position. A stop may beemployed to limit the downwardmovement of the vibrator. Such a stop is shown in the form of a pin 93on, thebracket 94 in the vibrator.

WVhen it is desiredto employ'the lower field )'of the ribbon,,theeccentric devi'ceis given'half a turn until the openin 91 engages withthe detent 88. This brings the curvedS portion of the eccentric deviceuppermo t, the result being that there is or may be no lost motionbetween the lever 38 and the vibrator. The vibrator thereforewillparticipate in the full extent of movement ofthe operating lever -38and the rib- .bon will be lifted far enough to bringits lower field toprinting position.

In the different forms of my invention above described provision is madefor moving the 'vibrator predetermined extents whenever the printingkeys are operated. It mayat times be desired, as in 'mimeograph work, todispense with movement of the vibrator altogether during operations ofthe printing keys. My invention lends itself readily to such aconstruction and in Figs. 14, 15 and 16 I have shown one means ofaccomplishing this result. These figures illustrate an eccentric device95 having curved working faces 96 and flat or straight faces 97 and 98oppositely disposed to each other. The device 95 may be rotativelymounted on e the universal bar in the manner shown in from t e cehter ofrotation 99 of the eccentric device nd when the latter is positioned asshown in Fig. 15, said faces 96 contact with the'to' and bottom of theopening in the strap, causing a close fit of the eccentric devicetlierein. As a result there will be no lost motion and'the link 42 willparticipate in the lfullextent of movement of the universal bar,while'the vibrator will be'moved up far'ienough to bring the red field bof the ribbon! to the printing point.

when the device 95 is set so that the as; 98 is uhdermost asjshown inFig. 14, then the univeri sal bar will move downwardly a tance'represented by the numeral 100 before picking up the strap andthevibrator will only, be moved far enough to render the upper ribbonfield a operative. The face 9'? is nearer the center of rotation of'theeccentric device than is'the face 98. As a result, when the eccentricdevice is set as shown in Fig. 16 with the face 97 lowermost, theuniversal bar will complete itsdownward movement I before the face 97contacts'with the bottom tact with the bottomof the strap just beforecompletion of the downward movement of the eccentric, thus moving thelink 42.

slightly but not enough to cause the ribbon to move into the path of thetypes. Consequently the link 42 will not be affected and the vibratorand ribbon will remain in normal position belowthe printing point.

The construction shown in liigs. 14 to 16 may-be employed at-a-nydesired point in the train of connections betwen the keys and thevibrator.

The modifications shown herein and not claimed specificallyin 1 thiscase will be claimed in separate applications.

One of the essentially novel features of "my invention resides in theemployment of what I have designated the eccentric connection betweencoiiperating parts of the of its operating sides or members is fartherfrom the center of rotation of the device than another of its operatingsides or members. I do not wish to be limited to the use of thiseccentric device at any particular location in the train of devicesconstituting the ribbon mechanism because, as is evident, it may beemployed at any desired locality between the ribbon vibrator and theuniversal bar or other device employed primarily to actuate the ribbonvibrating mechanism as an entirety. I have shown this eccentric devicein use at three different places in the mechanism, viz., theplace ofconnection between the upper'end of the link and the rear end of theribbon vibrator lever; the place of connection between the universal barframe and the lower end of the link; and also at the place of connectionbetween the forward end of the vibrator lever and the lower end of theribbon vibrator: But it is evident that this eccentric c gnnection mightbe otherwise located,and v rious other modifications will readily suggest themselves to those Skilled in the art and especially in-efi'ortsto adapt the idea to other styles of ribbon mechanisms. I thereforedesire to claim this feature of my invention as-broadly as possible.

- device; and in Figs. 12 and 13 the ribbon vibrator 32 may beconsidered as the actuated device and its lever 38 as the actuatingdevice. It will also be observed that the eccentric connection betweenany two devices remains always connected with said devices at thesameplace. Unlike prior devices it is not a device which is shiftable toa new position relatively to the length of an arm of a lever so as tovary the point or place of connection of an actuating device to saidlever arm and in that way lengthen or shorten the lever and vary thepoint of application of the power and the leverage on the ribbonvibrator. It will be observed furthermore that the faces or members ofthe connecting device cooperate each with the same portion of the partwith which said connecting device isas'sociated.

Various other changesbesidesthose described may bemade without departingfrom my invention. For example, the part 49 of the connecting member mayin some instances have forms other than that shown in the presentinstance.
